The digital output of dual-mode connectors can also be specifically selected and forced on; eg., 'video=DVI-I-2:D'. However, in this case, the connector->status will be mistakenly set to connector_status_disconnected, and the connector will not be mode set. Fix the connector->status when connector->force is DRM_FORCE_ON_DIGITAL. Note that this seems to have been broken ever since the introduction of the connector forcing support in commit d50ba256b5f1478e15accfcfda9b72fd7a661364 Author: Dave Airlie Date: Wed Sep 23 14:44:08 2009 +1000 drm/kms: start adding command line interface using fb.
